The portion weights come from the USDA household measures for this food. Carb units = carbs of the portion ÷ 10, 12 or 15 g. Glycemic load = GI × carbs of the portion ÷ 100.

Glycemic index

GI 70. This is the mean of 3 measurements in the 2021 international GI tables. The measured values are from 61 to 77.

* This value includes measurements from the second table of the paper: studies with method deviations, such as few participants, participants with diabetes, or wide variation. Use it as a rough guide.
